The thing is that, when I going to authenticate using the API, the error shows is this:

Error info: [Errno 8] nodename nor servname provided, or not known
[Errno 8] nodename nor servname provided, or not known
Error info: SmartWebSocket.__on_close() takes 2 positional arguments but 4 were given
SmartWebSocket.__on_close() takes 2 positional arguments but 4 were given

While the two files which manage the auth and stream of data from the web socket are as follows:

auth.py

from SmartApi import SmartConnect
import config

def authenticate():
    obj = SmartConnect(api_key=config.API_KEY)
    data = obj.generateSession(config.CLIENT_ID, config.PASSWORD, config.TOTP)

    refreshToken = data['data']['refreshToken']

    feedToken = obj.getfeedToken()
    return obj, refreshToken, feedToken

data_stream.py

import json
from SmartApi import SmartWebSocket
import config
import auth

def stream(feedToken, clientCode):
    ss = SmartWebSocket(feedToken, clientCode)
    def on_message(ws, message):
        print("Ticks: {}".format(message))
    def on_open(ws):
        print("on open")
        ss.subscribe("mw", config.TOKEN)
    def on_error(ws, error):
        print(error)
    def on_close(ws, close_status_code, close_msg):
        print("### Connection closed ###")
        print(f"Status code: {close_status_code}, Message: {close_msg}")

    ss._on_open = on_open
    ss._on_message = on_message
    ss._on_error = on_error
    ss._on_close = on_close
    ss.connect()
obj, refreshToken, feedToken = auth.authenticate()
stream(feedToken, config.CLIENT_ID)

It would be great if the issue of mine is resolved at the earliest. Thanks...
